Maybe early rising is an effect of being emotionally healthy, not a cause. Someone that naturally rises early might be in good emotional shape, but someone that is not healthy will not magically become healthier by just forcing him or herself to rise earlier. I think we are mixing cause and effect here. It might also not be correlated. I mean, it may well be cultural, to rise earlier when you are feeling fine, but those two facts, early rising and emotional health, might not have a cause and effect relationship at all.
